Measured pressure differential
Measured pressure differential
The air flow for boosted ventilation can be
adjusted by means of the valve in the sound
attenuator or throttling box. If the valve is to be
adjusted, you must measure the pressure in the
valve as illustrated below. The control damper
can be opened fully by hand in order to
facilitate the measurement. If the measurement
is performed with the sound attenuator or
commissioning section open, the true air flow
from the cooker hood will be about 3 l/s lower
than the measured value, when sizing is 25 l/s.
See the control curve for boosted ventilation
in the “Technical data” section.
1. General
The cooker hood has a central role in the
home ventilation system. It is important that
the cooker hood removes cooking odours ef-
ficiently and quietly.
Thanks to an elegant and distinct design,
all Swegon CASA cooker hoods blend in as
part of the furnishings in a modern kitchen.
Particular attention has been directed during
the design phase to user comfort and the
hoods feature smooth, easy-to-clean surfaces.
The metal grease filters are also easy-to-
clean. The cooker hood’s lighting consists of
maintenance-free LED lamps (4000 K).
2. Installation
All cooker hoods are equipped with an exter-
nal power source, that also serves as a main
power switch. The wall socket, intended for
the connection of the cooker hood, must be
installed so it is easily accessible.
See the detailed instructions in the separate
installation instructions enclosed with the
cooker hood.
3. Commissioning
The cooker hood is ready for use immedi-
ately after you have installed it, provided
that the cooker hood is not used for
general ventilation.
The basic air flow setting is made (damper
closed) by opening the existing hole in the
damper. On delivery, all the holes for basic air
flow are sealed. See the control curve for basic
ventilation in the “Technical data” section.
The air flow is obtained by measuring the
pressure differential across the control damper
inside the cooker hood and then reading
the air flow that corresponds to the control
position. Measure the pressure in the hole
next to the control damper arm as shown in
the diagram to the right. There is a rubber
bushing with a hole to read the air flow in the
cooker hood’s accessory bag.
